Dodgers pitcher Hiroki Kuroda suffered a concussion when he was hit in the head by a line drive during a 4-3 loss to the Diamondbacks on Saturday night, but tests revealed no fracture or internal bleeding, according to an Associated Press report. ?Amazingly, things look really pretty good,? Dodgers athletic trainer Stan Conte said. ?The fact that he didn?t lose consciousness is a very good sign.? Kuroda was to spend the night at St. Joseph?s Hospital for observation.
